Executive summary

The main objective of this project is to explore the role of gene expression and structural variation in contributing to an adaptive traits (bud phenology) in a keystone forest tree species: oak.

  1. We will generate sequences (RNAseq and pool-seq data) at the population level to study local adaptation, a process whereby a population becomes better suited to its habitat. The selected populations are located along two elevation clines in the Pyrenees, showing strong phenotypic differences in terms of average bud burst date.
  2. We will also generate sequences within a structured populations (endo- and eco-dormant buds sampled on 150 full-sibs) to decipher the genetic architecture of gene expression and how it relates to bud phenology QTLs.
